Abstract

Purpose

This study aims to focus on a short review on recent results dealing with the mechanical modelling and experimental characterization of a novel class of tensegrity structures, named class θ = 1 tensegrity prisms. The examined structures exhibit six bars connected by two disjoint sets of strings.

Design/methodology/approach

First, the self-equilibrium problem of tensegrity θ = 1 prisms is numerically investigated for varying values of two aspect parameters and, next, their prestress stability is studied. The mechanical behavior of the examined structures in the large displacements regime under uniform compression loading is also numerically computed through a path-following procedure. Finally, the predicted constitutive response is validated through experimental tests.

Findings

The presented results highlight that the examined structures exhibit a large number of infinitesimal mechanisms from the freestanding configuration, and reveal that they exhibit tunable elastic response switching from stiffening to softening.

Originality/value

This multi-faceted elastic response is in agreement with previous literature results on the elastic response of minimal tensegrity prism, and suggests that such units can be usefully used as non-linear springs in next-generation tensegrity metamaterials.

Abstract

The optimisation of forest fuels supply chain involves several entities actors, and particularities. To successfully manage these supply chains, efficient tools must be devised with the ability to deal with stakeholders dynamic interactions and to optimize the supply chain performance as a whole while being stable and robust, even in the presence of uncertainties. This work proposes a framework to coordinate different planning levels and event-based models to manage the forest-based supply chain. In particular, with the new methodology, the resilience and flexibility of the biomass supply chain is increased through a closed-loop system based on the system forecasts provided by a discrete-event model. The developed event-based predictive model will be described in detail, explaining its link with the remaining elements. The implemented models and their links within the proposed framework are presented in a case study in Finland and results are shown to illustrate the advantage of the proposed architecture.

Abstract

Purpose

Although student-centered learning (SCL) has been encouraged for decades in higher education, to what level instructors are practicing SCL strategies remains in question. The purpose of this paper is to investigate a university faculty’s understanding and perceptions of SCL, along with current instructional practices in Qatar.

Design/methodology/approach

A mixed-method research design was employed including quantitative data from a survey of faculty reporting their current instructional practices and qualitative data on how these instructors define SCL and perceive their current practices via interviews with 12 instructors. Participants of the study are mainly from science, technology, engineering and mathematics (STEM) field.

Findings

Study results show that these instructors have rather inclusive definitions of SCL, which range from lectures to student interactions via problem-based teamwork. However, a gap between the instructors’ perceptions and their actual practices was identified. Although student activities are generally perceived as effective teaching strategies, the interactions observed were mainly in the form of student–content or student-teacher, while student–student interactions were limited. Prevailing assessment methods are summative, while formative assessment is rarely practiced. Faculty attributed this lack of alignment between how SCL could and should be practiced and the reality to external factors, including students’ lack of maturity and motivation due to the Middle Eastern culture, and institutional constraints such as class time and size.

Research limitations/implications

The study is limited in a few ways. First regarding methodological justification the data methods chosen in this study were mainly focused on the faculty’s self-reporting. Second the limited number of participants restricts this study’s generalizability because the survey was administered in a volunteer-based manner and the limited number of interview participants makes it difficult to establish clear patterns. Third, researching faculty members raises concerns in the given context wherein extensive faculty assessments are regularly conducted.

Practical implications

A list of recommendations is provided here as inspiration for institutional support and faculty development activities. First, faculty need deep understanding of SCL through experiences as learners so that they can become true believers and implementers. Second, autonomy is needed for faculty to adopt appropriate assessment methods that are aligned with their pedagogical objectives and delivery methods. Input on how faculty can adapt instructional innovation to tailor it to the local context is very important for its long-term effectiveness (Hora and Ferrare, 2014). Third, an inclusive approach to faculty evaluation by encouraging faculty from STEM backgrounds to be engaged in research on their instructional practice will not only sustain the practice of innovative pedagogy but will also enrich the research profiles of STEM faculty and their institutes.

Social implications

The faculty’s understanding and perceptions of implementing student-centered approaches were closely linked to their prior experiences – experiencing SCL as a learner may better shape the understanding and guide the practice of SCL as an instructor.

Originality/value

SCL is not a new topic; however, the reality of its practice is constrained to certain social and cultural contexts. This study contributes with original and valuable insights into the gap between ideology and reality in implementation of SCL in a Middle Eastern context.

Abstract

Purpose

This paper aims to inform strategies to enhance public procurement opportunities for women-owned small- and medium-sized enterprises (SMEs). To do so, the study examines two research questions: To what extent are women-owned enterprises under-represented among SME suppliers to government; and Do barriers to public procurement – as perceived by SME owners – differ across gender?

Design/methodology/approach

The study draws on the resource-based view (RBV) of the firm and on theories of role congruity and social feminism to develop the study’s hypotheses. Empirical analyses rely on comparisons of a sample of 1,021 SMEs that had been suppliers to government and 9,376 employer firms that had not been suppliers to government. Data were collected by Statistics Canada and are nationally representative. Logistic regression analysis was used to control for systemic firm and owner differences.

Findings

Controlling firm and owner attributes, majority women-owned businesses were underrepresented as SME suppliers to government in some, but not all sectors. Women-owned SMEs in Wholesale and Retail and in Other Services were, ceteris paribus, half as likely as to be government suppliers as counterpart SMEs owned by men. Among Goods Producers and for Professional, Scientific and Technical Services SMEs, there were no significant gender differences in the propensity to supply the federal government. “Complexity of the contracting process” and “difficulty finding contract opportunities” were the obstacles to contracting cited most frequently.

Research limitations/implications

The limitations of using secondary analyses of data are well documented and apply here. The findings reflect only the perspectives of “successful bidders” and do not capture SMEs that submitted bids but were not successful. Furthermore, the survey did not include questions about sub-contractor enterprises, data that would likely provide even more insights about SMEs in government supply chains. Accordingly, the study could not address sub-contracting strategies to increase the number of women-owned businesses on government contracts. Statistics Canada’s privacy protocols also limited the extent to which the research team could examine sub-groups of small business owners, such as visible minorities and Indigenous/Aboriginal persons. It is also notable that much of the SME literature, as well as this study, define gender as a dichotomous (women/female, men/male) attribute. Comparing women/female and men/males implicitly assumes within group homogeneity. Future research should use a more inclusive definition of gender. Research is also required to inform about the obstacles to government procurement among the population of SMEs that were unsuccessful in their bids.

Practical implications

The study provides benchmarks on, and directions to, enhance the participation of women-owned SMEs or enterprises in public procurement. Strategies to support women-owned small businesses that comply with United Nations Sustainable Development Goals are advanced.

Social implications

The study offers insights to reconcile economic efficiency and social (gender equity) policy goals in the context of public procurement. The “policy-practice divides” in public procurement and women’s enterprise policies are discussed.

Originality/value

The study is among the first to use a feminist lens to examine the associations between gender of SME ownership and public procurement, while controlling for other salient owner and firm attributes.

Abstract

With the proliferation of international education initiatives, research into the transfer of pedagogy across cultures is essential to ensure that quality education is delivered in a culturally accessible form. One of the factors impeding such research is the lack of widely accepted theoretical frameworks (Dimmock & Walker, 2005). This paper examines the development and effectiveness of a cross cultural framework that was used to compare a Business program at a Canadian College with its branch campus in Qatar (Prowse & Goddard, 2010). Findings are compared to results in the literature to gauge the robustness of the framework. The framework developed in the study was found to be a helpful means of allowing a comparison of pedagogy across two cultures.

Abstract

Purpose

The purpose of this study is to describe latent classes explaining the innovation logic in the Finnish construction companies. Innovativeness is a driver of competitive performance and vital to the long-term success of any organisation and company.

Design/methodology/approach

Using finite mixture structural equation modelling (FMSEM), the authors have classified innovation logic into latent classes. The method analyses and recognises classes for companies that have similar logic in innovation activities based on the collected data.

Findings

Through FMSEM analysis, the authors have identified three latent classes that explain the innovation logic in the Finnish construction companies – LC1: the internal innovators; LC2: the non-innovation-oriented introverts; and LC3: the innovation-oriented extroverts. These three latent classes clearly capture the perceptions within the industry as well as the different characteristics and variables.

Research limitations/implications

The presented latent classes explain innovation logic but is limited to analysing Finnish companies. Also, the research is quantitative by nature and does not increase the understanding in the same manner as qualitative research might capture on more specific aspects.

Practical implications

This paper presents starting points for construction industry companies to intensify innovation activities. It may also indicate more fundamental changes for the structure of construction industry organisations, especially by enabling innovation friendly culture.

Originality/value

This study describes innovation logic in Finnish construction companies through three models (LC1–LC3) by using quantitative data analysed with the FMSEM method. The fundamental innovation challenges in the Finnish construction companies are clarified via the identified latent classes.

Abstract

Purpose

At the beginning of the 21st century, a new class of information workers, the “information have-less” has risen. This class of workers alleviates the influence of information and communication technologies (ICTs) revolution on poverty and unemployment. The purpose of this study is to investigate the presence of this class of workers in Egypt and assess the size and potential growth of this category of workers.

Design/methodology/approach

The study clarifies the conceptual framework of the new division of labor, in the information age. The Central Agency for Public Mobilization and Statistics, American Chamber of Commerce in Egypt, Ministry of Communications and Information Technology and Information and Decision Support Center websites provided secondary data for this study. These data are used to assess the size of “the information have less” in Egypt.

Findings

The division of work and class, in the 21st century, depends on the level of skills possessed to work with ICTs. So, class and labor nowadays could be divided into self-programmable labor (Innovators). Information have-less labor class, adding value to the economy by learning skills and presenting repetitive work. Generic labor class, who cannot work with ICTs, and work in jobs, that do not need computers or other ICTs. The study has shown that the “information have-less” labor class is present in Egypt since the beginning of the 21st century, in all its categories; entrepreneurism, the service sector and the manufacturing sector. There are approximately 50% of this labor class in the service sector and only 13% of the information have-less works in manufacturing sector despite the great opportunities that Egypt has to expand manufacturing to absorb more employment. The inclusion of information technology (IT), in all domains, has not decreased employment in Western countries but has reallocated information have-less employment toward the service sector, and there would probably be the same effect in Egypt.

Practical implications

The study highlights the need for Egyptian policymakers to encourage the manufacturing and service sectors to provide huge working opportunities. The Egyptian government has to change the educational policies, at all stages, to include digital learning skills so IT can be incorporated in a wide range of economic activities. Further research includes: conducting a survey to measure the contribution of the entrepreneurial part of the information have-less employment in Egypt. In addition, a model may be developed, by the researcher to examine the reallocation of employees in Egypt.

Originality/value

Studying employment, in Egypt, using the conceptual framework of the information age is rarely being done.

Abstract

This chapter looks at the discursive dimension of the working environment in research and higher education organizations; more specifically at neoliberal managerial discourse and at how it participates in shaping the way researchers, teachers and support staff perceive themselves and their experiences. It is based on a multiple case study and combines an intersectional and a socio-clinical approach. The empirical data is constituted by in-depth interviews with women conducted in Ireland and Chile, and includes some observations made in France. A thematic analysis of individual narratives of self-ascribed experiences of being bullied enables to look behind the veil drawn by managerial discourse, thus providing insights into power vectors and power domains contributing to workplace violence. It also shows that workplace bullying may reinforce identification to undervalued social categories. This contribution argues that neoliberal managerial discourse, by encouraging social representations of “neutral” individuals at work, or else celebrating their “diversity,” conceals power relations rooting on different social categories. This process influences one’s perception of one’s experience and its verbalization. At the same time, feeling assigned to one or more of undervalued social category can raise the perception of being bullied or discriminated against. While research has shown that only a minority of incidents of bullying and discrimination are reported within organizations, this contribution suggests that acknowledging the multiplicity and superposition of categories and their influence in shaping power relations could help secure a more collective and caring approach, and thus foster a safer work culture and atmosphere in research organizations.

Abstract

Purpose

This article describes an effort to ease the tension between boundary spanning roles for interns participating in a yearlong Professional Development School (PDS) program. In order to do this, the structure of a Social Studies Methods course was revised to mimic a professional learning community (PLC) and assignments were not evaluated for grades.

Design/methodology/approach

A conceptual paper that relies on self-reflection as well as student reaction, work samples and survey data.

Findings

The findings demonstrate both practices contribute to a collegial and less stressful environment for interns, while not affecting the quality of work submitted.

Originality/value

This paper highlights two of the nine NAPDS essentials, Professional Learning and Leading (3) and Boundary Spanning (8), and describes the ways both are incorporated and addressed in a PDS situated methods course. Describing course revisions, including the implementation of an ungrading practice, provides examples for potential replication.
